How to troubleshoot a download error in iPreFlight3?

 The Download screen in iPreFlight includes several options. Two of the most important are "Clear & Refresh" and "Check for Updates".

Clear & Refresh

What it does:

• Completely wipes all previously downloaded data from the device and resets the download screen.

What happens next:

• Prompts the user for confirmation before proceeding.
• Deletes all downloaded files.
• Unlocks any previously locked downloads.
• Contacts APG servers to retrieve the latest versions of:
  • Airfield database
  • Aircraft downloads
  • Weight & balance files

When to use it:

• Use this if the download screen appears incorrect, files are missing, or downloads aren’t working properly. It gives you a clean slate.

Check for Updates

What it does:

• Checks for any new or updated files without deleting existing downloads.

What happens next:

• Contacts APG servers to check for updates.
• Displays available updates for airfield and aircraft data.
• Automatically downloads the latest weight & balance files.

When to use it:

• Ideal for quick updates—such as when a customer requests a flap setting change or weight & balance update.

• Clear & Refresh: Wipes and resets everything.
• Check for Updates: Keeps existing data and adds only what’s new.
• Speed: Check for Updates is faster and less disruptive.
